File Shield

This Article Applies to:

  • AVG Business Cloud Console
  • AVG Business On-Premise Console

File Shield is the main layer of active protection in AVG Business Antivirus. It scans programs and files saved on devices for malicious threats in real-time before allowing them to be opened, run, modified, or saved. If malware is detected, File Shield prevents the program or file from infecting devices.

We strongly recommend you always keep this shield turned on and only make configuration changes if you have an advanced understanding of malware protection principles.

Windows

Scan Behavior Tab

Scan when executing: select whether to scan programs, scripts, and/or libraries when the files or programs are executed

Scan when opening: select whether to scan documents, documents with custom extensions (you input), and/or all files when the documents or files are opened

Scan when attaching: select whether to scan auto-run items and/or diskette boot sectors when removable media is attached

Scan when writing: select whether to scan files when writing (default extensions, custom extensions, or all files), and also whether or not to scan files on remote shares or removable media when the files are created or modified

Exclusions Tab

Configure the list of locations that are not scanned by File Shield, when they are Read, Written, and/or Executed.

For more information on configuring exclusions for File Shield, see File Shield Exclusions.

Exclusions that you specify on this screen only apply to File Shield and do not affect any other scans or Shields. To exclude a location from all AVG Business Antivirus scans, see Configuring Standard Antivirus Exclusions.

Actions Tab

Control what actions are taken by AVG when a virus, potentially unwanted program (PUP), or suspicious file is detected.

Main Action: select the first action your Antivirus will take between Fix Automatically, Move to chest, Repair, Ask, Delete, or No Action.

If, for whatever reason, AVG cannot complete the main action, it will attempt the action selected under If the action fails, use.

Options: choose whether to show notifications when File Shield takes action against a detected threat, and/or to perform the selected action upon restart.

Processing of infected archives: choose whether to only remove the packed file from the archive (and if that fails, do nothing), remove the packed file from the archive (and if that fails, remove the entire archive), or to remove the entire archive.

Packers Tab

Configure which archive (packer) files AVG Business Antivirus should try to unpack during the scanning process. Unpacked files can be better analyzed for malware by File Shield. Unpacking a file is the same as extracting a file from an archive. Original archives, including the files contained within, remain intact when being processed by your Shield.

You can select All packers, or specific packer files from the extensive list by checking the boxes.

Sensitivity Tab

Adjust the sensitivity of the AVG Business Antivirus scan for File Shield.

Heuristics Sensitivity: Heuristics enable Antivirus to detect unknown malware by analyzing code for commands that may indicate malicious intent. The default setting is Normal. With higher sensitivity, Antivirus is more likely to detect malware, but also more likely to make false-positive detections that incorrectly identify files as malware. Code emulations unpack and test suspected malware in an emulated environment where the file cannot cause damage to devices. Use code emulation is enabled by default.

Sensitivity: choose to test whole files, which will cause the scan to be slower but more extensive.

PUP and suspicious files: choose whether or not to scan for Potentially Unwanted Programs (PUPs)

Report File

Customize the content of the Shield-specific scan report file, such as which items are included, the file name, and file type. The report is saved in one of the following locations:

  • Windows 10, Windows 8.1, Windows 8, Windows 7, or Windows Vista: C:\ProgramData\Avg\antivirus\report
  • Windows XP: C:\Documents and Settings\All Users\Application Data\Avg\antivirus\report
